Algebra Examples
y=1x
Step 1
Set the denominator in 1x equal to 0 to find where the expression is undefined.
x=0
Step 2
The domain is all values of x that make the expression defined.
Interval Notation:
(-∞,0)∪(0,∞)
Set-Builder Notation:
{x|x≠0}
Step 3
The range is the set of all valid y values. Use the graph to find the range.
Interval Notation:
(-∞,0)∪(0,∞)
Set-Builder Notation:
{y|y≠0}
Step 4
Determine the domain and range.
Domain: (-∞,0)∪(0,∞),{x|x≠0}
Range: (-∞,0)∪(0,∞),{y|y≠0}
